1. Field of the Invention
The present invention is directed generally to systems and methods for providing wireless systems, and more specifically, to intelligent speaker systems including wireless audio and wireless communication features.
2. Description of the Related Art
In the past several years, wireless communication has become increasingly popular. Wireless communication encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, and wireless networking. Other examples of applications of radio wireless technology include global positioning system (GPS) units, garage door openers, wireless computer mice, keyboards and headsets, headphones, speakers, and radio receivers.
One popular wireless communication technology is Bluetooth®, a technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices, creating personal area networks (PANs). Bluetooth® is often used to transmit audio signals from a transmitting device (e.g., a mobile phone, laptop, etc.) to a receiving device (e.g., headset, speakers, etc.).
Embodiments of the present invention are directed to systems and methods for providing a universal distributed audio system including an integrated wireless repeater. In some embodiments, the system comprises an intelligent speaker system capable of receiving wireless audio signals (e.g., Bluetooth®, AirPlay®, etc.) from a wireless consumer device, decoding the received audio signals, and playing the resulting audio in a room of a venue. Control of the intelligent speaker system may be provided via an application executing on a wireless consumer device, such as a smart phone, laptop, tablet computer, desktop computer, television, etc. In other embodiments, control may be provided by a custom control device, such as a remote control module. In some embodiments, the application executing on the mobile computing devices may allow for source selection allowing the intelligent speaker system to toggle through two or more various wireless audio sources streaming audio signals to the intelligent speaker system. As discussed in further detail below, various embodiments of the intelligent speaker system include integrated wireless communication capabilities that allow the intelligent speaker system to perform as a wireless access point or wireless repeater to extend the coverage area of a wireless communications network (e.g., throughout a home or office building).
As will also be described in detail below, the intelligent speaker systems, or more generally, fixed wireless audio devices, communicate wirelessly with the wireless consumer devices. Many known wireless consumer devices are offered by different service providers. The devices operate in accordance with different known communication standards, such as CDMA, GSM, 3G, 4G, WiMAX, or the like. Operation of these various wireless devices is well known in the art, and need not be described in greater detail herein. These conventional devices operate at assigned frequencies. For example, some cell phones operate in the 800 MHz band while PCS devices operate in the 1.9 GHz band. Some devices are multimode and can operate in an analog or digital mode, and are capable of operating in different frequency bands. In addition, the wireless consumer devices may contain short-range transceivers (as compared to cellular transceivers), such as Bluetooth® or Wi-Fi® (IEEE 802.11). As will be discussed in greater detail below, short-range communication devices may be used within a venue (e.g. a home or office) to transmit audio signals to and provide control of the fixed wireless audio devices of the present invention.
As illustrated in
Each of the fixed wireless audio devices 104A-104F is configured to have short-range communication capabilities. The term “fixed wireless audio device,” as used herein, refers to the fact that the device is stationary during operation rather than any reference to its size or relative portability, however, the device may typically be housed in a small portable package or housing. The fixed wireless audio devices 104A-104F may be integrated into a single package that may be fixedly mounted in or on a wall, floor, or ceiling of the venue 102.

The fixed wireless audio device 104A further includes a speaker 124 coupled to an amplifier 126 configured to drive the speaker. The speaker 124 is configured to output sound, such as music, voice, or the like. In some embodiments, the fixed wireless audio device 104A also includes a visual output 128, such as one or more light emitting diodes (LED), a display, or the like. As discussed below, the visual output 128 may be used to provide visual signals to users within the same room as the fixed wireless audio device 104A.
The fixed wireless audio device 104A further includes a regulated power supply or converter 130 configured to receive power directly from an AC power source 132 of the venue 102. In some embodiments, the power supply 130 may be in the form of a switched-mode power supply (SMPS), but other types of power supplies may be used. For example, as shown in
The fixed wireless audio device 104A also includes a wireless repeater control module 140 which allows the fixed wireless audio device to operate as a wireless repeater, also referred to as a wireless range extender. In general, the wireless repeater control module 140 is operative to receive an existing signal from a wireless router or access point of a primary network and to rebroadcast it to essentially create a second network. Those outside of the primary network but within the range of the fixed wireless audio device 104A will be able to connect through the new “repeated” second network. As can be appreciated, this wireless repeater functionality may be used to improve signal range and strength within the venue 102.

As illustrated in
The wireless consumer device 106A also includes a transmitter 154 and a receiver 156. As known in the art, the receiver 156 of the wireless consumer device 106A searches for a base station with which to communicate. Communication with a base station allows the wireless consumer device 106A to access one or more data networks (e.g., the Internet). In some implementations, the transmitter 154 and the receiver 156 share common circuitry and may be implemented as a transceiver 158. The transmitter 154 and receiver 156 are coupled to an antenna 160. Commonly, the antenna 160 of the wireless consumer device 106A is implemented as an omnidirectional antenna to provide the greatest possibility of detecting a suitable base station with which to communicate.
The wireless communication device 106A also includes one or more input devices 162 (e.g., a keypad, touch screen, microphone, and the like), audio output 164 (e.g., a speaker), and a display output 166 (e.g., an LCD display). As discussed below, the input device 162 and display output 166 may be used as a user interface by a user of the system 100 to control the operation thereof.
The wireless consumer device 106A also includes one or more short-range transceivers 168 coupled to an antenna 170. The short-range transceivers 168 may also be implemented as one or more separate transmitters and receivers. The wireless consumer device 106A may include, by way of example, a Bluetooth® transceiver and/or a Wi-Fi® transceiver (IEEE 802.11). Other conventional short-range transceivers may also be used. The short-range transceiver 168 in

Referring back to
When the wireless consumer device 106A comes within the range of the fixed wireless audio device 104A, the wireless consumer device detects the fixed wireless audio device and registers or associates therewith. This process may be referred to as “pairing.” In some protocols such as Bluetooth®, two devices need only be paired together manually once, and then the two devices can connect automatically thereafter. Once the wireless consumer device 106A is connected to the fixed wireless audio device 104A, the wireless consumer device may stream audio signals to the fixed wireless audio device for decoding and real-time playback through the speaker 124 (see
As a user 180A moves throughout the venue 102 with the wireless consumer device 106A, the wireless consumer device may move out of range of the fixed wireless audio device 104A and within the range of the fixed wireless audio device 104E located in room 3. As this occurs, the fixed wireless audio device 104E may pair with the wireless consumer device 106A so that the wireless consumer device initiates streaming of audible signals to the fixed wireless audio device 104E such that user's 180B audio may continue to play. In this example, each of the wireless consumer devices 106A-106E may stream audio signals to a nearby fixed wireless audio device 104, such that different users (e.g., user 180A and user 180B) throughout the venue 102 may utilize different fixed wireless audio devices 104A-104F simultaneously. For example, the user 180A of the wireless consumer device 106A in room 1 may utilize fixed wireless audio device 104A in room 1, while the wireless consumer device 106D in room 3 may utilize the fixed wireless audio device 104E located in room 3.
In some embodiments, the fixed wireless audio devices 104A-104F are operative to communicate data, control, and/or audio signals with each other. This may be accomplished through wired and/or wireless communication. For example, the fixed wireless audio devices 104A, 104B, and 104D-104F may communicate wirelessly with each other, whereas the fixed wireless audio device 104C may be configured to communicate with the fixed wireless audio device 104A via a wired connection 184. In this example, the user 180B of the wireless consumer device 106B in room 1 may stream audio signals to the fixed wireless audio device 104A also in room 1, which may then rebroadcast the audio signals to one or more other fixed wireless audio devices 104B-104F within the venue 102 using a combination of wireless communication (with devices 104B and 104D-104F) and wired communication (with device 104C). Thus, using a single wireless consumer device 1068, sound may be played throughout the venue 102.
The source selection module 194 is provided to allow the user to select which wireless consumer device 106A-106E is to be paired with a particular fixed wireless audio device 104A-104F at a given time. In some embodiments, the selection may be done manually. For example, the user may select a wireless consumer device 106 from a list of available wireless consumer devices. In some embodiments, the source selection module 194 may allow the user to configure a prioritization scheme for prioritized connection between the wireless consumer devices 106 and fixed wireless audio devices 104. For example, a parent may want his or her wireless consumer device 106 to have a higher priority for connection than a child's wireless consumer device.
In some embodiments, the source selection module 194 of the mobile application 192 is configured to automatically perform source selection based on one or more criteria. For example, the source selection module 194 may automatically select from a plurality of available wireless consumer devices 106A-106E based on the wireless consumer device that was most recently connected to the system 100. As another example, the source selection module 194 may automatically select from a plurality of available wireless consumer devices 106 based on the wireless consumer device that historically connects to the system 100 the most often, for the longest duration, etc. Those skilled in the art will recognize other criteria or combinations of criteria may be used by the source selection module 194 to automatically select an audio source.
The zone selection module 196 is configured to allow the user to select which zones of the venue 102 are to be active. For example, the user of the wireless consumer device 106A in room 1 may direct the zone selection module 196 to provide audio playback on all fixed wireless audio devices positioned in room 1 and room 2 only (i.e., devices 104A-104D). Another user of the wireless consumer device 106D located in room 3 may utilize the zone selection module 196 to instruct the system 100 to provide audio playback only on the fixed wireless audio device 104E located in room 3.
The zone selection module 196 may also allow users to configure schedules for the system 100. For example, if room 4 is a room in which a child sleeps, the user may utilize the zone selection module 196 to specify a rule that disables the fixed wireless audio device 104F in room 4 between the hours of 8 PM and 8 AM. As will be appreciated by those of skill in the art, the zone selection module 196 may be used to set other schedules as may be desired by users of the system 100.
The visual control module 198 may be used to control the visual output 128 (see
In some embodiments, the mobile application 192 includes an intercom module 200. The intercom module 200 is configured to receive audio signals from an audio input device 162 (e.g., a microphone) (see
In some embodiments, the mobile application 192 executing on a wireless consumer device 106 may communicate directly with one or more of the fixed wireless audio devices 104 using a suitable wireless protocol, such as Bluetooth® or Wi-Fi®. In other embodiments, the wireless consumer device 106 may communicate with a remote server 210 (see
Wireless consumer devices 228A-228C located in zone 2 are positioned out of the coverage area of the wireless access point 222 located in zone 1. In this example, a fixed wireless audio device 104G is mounted on a wall of zone 2. As described above, power is provided to the fixed wireless audio device 104G via an electrical cable 134G (e.g., Romex® cable) coupled to a junction box 136G of the electrical system of the venue 220. The wireless repeater control module 140 (see
The power supply 130 of the volume control unit 232 is coupled to a junction box 246 of the venue 234 via an electrical cable 248, as described above. The volume control unit 232 is configured to receive and transmit wireless signals using one or more communication protocols (e.g., Bluetooth®, AirPlay®, Wi-Fi®, and the like). In this embodiment, the volume control unit 232 is coupled to four speakers 250A-250D located in room 1 of the venue 234. In some embodiments, the volume control unit 232 includes an onboard amplifier 126 (see
In addition to wired connection with the speakers 250A-250D, the volume control unit 232 may also be operative to communicate wirelessly with a speaker 254, which is located in a room 2 of the venue 234. The speaker 254 includes wireless communication functionality, and is coupled to the electrical system of the venue 234 via an electrical cable 256 that is tied in to a junction box 258. The volume control unit 232 transmits audio signals via wired and wireless communications that are amplified and played back at the speakers 250A-250D and 254.
As with other embodiments discussed above, the volume control unit 232 and the speaker 254 positioned in room 2 of the venue 234 may function as wireless repeaters. As an example, a wireless consumer device 260 located in room 2 may be able to access the Internet 224 via a chain of wireless connections extending between the wireless consumer device 260, the speaker 254 in room 2, the volume control unit 232 in room 1, and the wireless access point 222 in room 1. Thus, the volume control unit 232 functions to extend the wireless coverage of the wireless access point 222.
In some embodiments, one or more fixed wireless audio devices 104 may include all of the components discussed above (see
The audio streamed from the wireless consumer devices 106 may include music, voice, or any other audio. For example, a user may utilize the system 100 to stream music from a media player application executing on a wireless consumer device 106 to speakers of the fixed wireless audio devices 104 located within a venue. As another example, a user may utilize the system 100 as a “hands free” speaker system for phone calls, wherein the voice of the person with whom the user is speaking is played on one or more fixed wireless audio devices 104 of the system. As yet another example, the audio may include white noise designed to mask sounds or keep conversations confidential, which may be desirable in venues such as libraries or doctors' offices.
The foregoing described embodiments depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermediary components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality.
While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from this invention and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this invention. Furthermore, it is to be understood that the invention is solely defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations).
Accordingly, the invention is not limited except as by the appended claims.
